Due to the huge waste of power resources in the process of electricity consumption, the application of energy-saving design technology in electrical automation has been produced, with the purpose of reducing the consumption of electric energy. Based on this, this paper takes the energy-saving design technology of electrical automation as the research object, mainly introduces the significance of energy-saving design technology of electrical automation, and analyzes the energy-saving design technology of electrical automation, hoping to provide reference for those in need.展开更多
